V.AISC 360-16 Double L E.5
Verify the available compressive strength of a double angle compression member without slender elements per the AISC 360-16 code.
Details
From reference 2:
Verify the strength of a 2L4×3-1/2×3/8 LLBB (3/4-in. separation) strut, ASTM A36, with a length of 8 ft and pinned ends carrying an axial dead load of 20 kips and live load of 60 kips. Also, calculate the required number of pretensioned bolted or welded intermediate connectors required.
ASTM A536: Fy = 36 ksi

Section classification reported is for the cross section and loadcase that produced the worst case design ratio for flexure/compression Capacity results. 2. Results for any Capacity/Check that is not relevant for a section/loadcase based on the code clause in AISC 360-16 will not be shown in the report. 3. Bending results are reported as being �about� the relevant axis (X/Y), while the results for shear are reported as being for shear forces �along� the axis. E.g : Mx indicates bending about the X axis, while Vx indicates shear along the X axis. *** ABBREVIATIONS ***: ====================== F-T-B = Flexural-Torsional Buckling L-T-B = Lateral-Torsional Buckling F-L-B = Flange Local Buckling W-L-B = Web Local Buckling L-L-B = Leg Local Buckling C-F-Y = Compression Flange Yielding T-F-Y = Tension Flange Yielding STAAD SPACE -- PAGE NO. 4 STAAD.PRO CODE CHECKING - AISC 360-16 LRFD (V1.2) ***************************************************** ALL UNITS ARE - KIP INCH (UNLESS OTHERWISE Noted). - Member : 1 |-----------------------------------------------------------------------------| | Member No: 1 Profile: LD L40356 (AISC SECTIONS)| | Status: PASS Ratio: 0.943 Loadcase: 3 | | Location: 0.00 Ref: Cl.E3 | | Pz: 120.0 C Vy: 0.000 Vx: 0.000 | | Tz: 0.000 My: 0.000 Mx: 0.000 | |-----------------------------------------------------------------------------| | COMPRESSION SLENDERNESS | | Actual Slenderness Ratio : 76.914 | | Allowable Slenderness Ratio : 200.000 LOC : 0.00 | |-----------------------------------------------------------------------------| | STRENGTH CHECKS | | Critical L/C : 3 Ratio : 0.943(PASS) | | Loc : 0.00 Condition : Cl.E3 | |-----------------------------------------------------------------------------| | SECTION PROPERTIES (LOC: 0.00, PROPERTIES UNIT: IN ) | | Ag : 5.360E+00 Axx : 2.625E+00 Ayy : 3.000E+00 | | Ixx : 8.350E+00 Iyy : 1.541E+01 J : 2.512E-01 | | Sxx+: 6.950E+00 Sxx-: 2.984E+00 Zxx : 5.417E+00 | | Syy+: 3.978E+00 Syy-: 3.978E+00 Zyy : 7.107E+00 | | Cw : 7.750E-01 x0 : 0.000E+00 y0 : -1.014E+00 | |-----------------------------------------------------------------------------| | MATERIAL PROPERTIES | | Fyld: 36.000 Fu: 58.000 | |-----------------------------------------------------------------------------| | Actual Member Length: 96.000 | | Design Parameters (Rolled) | | Kx: 1.00 Ky: 1.00 NSF: 1.00 SLF: 1.00 CSP: 32.00 | |-----------------------------------------------------------------------------| | COMPRESSION CLASSIFICATION (L/C: 3 LOC: 96.00) | | λ λp λr CASE | | Flange: NonSlender 9.33 N/A 12.77 Table.B4.1a.Case3 | | Web : NonSlender 10.67 N/A 12.77 Table.B4.1a.Case3 | | | | FLEXURE CLASSIFICATION (L/C: 3 LOC: 96.00) | | λ λp λr CASE | | Flange: Compact 9.33 15.33 25.83 Table.B4.1b.Case12 | | Web : Compact 10.67 15.33 25.83 Table.B4.1b.Case12 | |-----------------------------------------------------------------------------| STAAD SPACE -- PAGE NO. 5 STAAD.PRO CODE CHECKING - AISC 360-16 LRFD (V1.2) ***************************************************** ALL UNITS ARE - KIP INCH (UNLESS OTHERWISE Noted). - Member : 1 Contd. |-----------------------------------------------------------------------------| | CHECKS FOR AXIAL TENSION | |-----------------------------------------------------------------------------| | TENSILE YIELDING | | DEMAND CAPACITY RATIO REFERENCE L/C LOC | | 0.000 173.7 0.000 Cl.D2 3 0.00 | | | | Intermediate Results : | | Nom.
